A weft guidance tube for a fluid weft insertion system of weaving apparatus includes an elongated member having a longitudinal channel therein. A plurality of segments are juxtaposed in the channel. Each of the segments includes a base and an upper end, with the upper end having an aperture therein and an exit slot extending from the aperture. The base of each segment is wider in cross-section than the upper end thereof. Connecting pins project outwardly from one side of each base to thereby permit connection of adjoining segments to each other. When so connected the apertures and exit slots of all of the segments arranged in the channel are in proper alignment and the upper end of each segment is spaced apart from the upper end of adjoining segments by a distance goverend by the width of bases of the segments. The plurality of segments are secured to the channel by suitable gripping means.
A weft guidance tube for a fluid weft insertion system comprising, an elongated member having a longitudinal channel therein, a plurality of segments juxtaposed in said channel, each said segment including a base and an upper end, said upper end having an aperture therethrough and an exit slot extending from said aperture, connecting means on each segment for connecting each segment to an adjacent segment with the apertures and exit slots of said segments being in alignment, the base of each said segment being wider in cross-section than the upper end thereof to thereby space said upper ends from each other when said segments are juxtaposed, and means for securing said plurality of segments in said channel.
A segment for use in a weft guidance tube wherein a fluid and weft entrained in the fluid are projected into said tube comprised of a plurality of such segments for delivery through the shed of loom comprising;
